Calculate the change in entropy of the system when 10.0 g of ice at -10.0C is converted into water vapour at 115.0C and a constant pressure of 1 bar. The molar constant-pressure heat capacities are: Cp.m(H2O(s))=37.6 J K-1 mol-; Cp,m(HO(1))=75.3 J K-1 mol-; and Cp,m(HO(g))=33.6 J K-1 mol-1. The standard enthalpy of vaporisation of HO(l) is 40.7 kJ mol-, and the standard enthalpy of fusion of HO(1) is 6.01 kJ mol-, both at the relevant transition temperatures. The melting and boiling points of water at 1 bar are 0C and 100C, respectively. The molecular mass of water is 18.02 g mol-
